A class I two lane highway is on level terrain with passing permitted
throughout. The highway has 11 ft lanes with 4 ft shoulders. There are 16 access points
per mile. The base FFS is 60 mi/h. The highway is oriented north and south, and
during the peak hour, 440 vehicles are going northbound and 360 vehicles are going
southbound. If the PHF is 0.87 and there are 4% large trucks, 3% buses, and 1%
recreational vehicles, what is the level of service.
Given:
ATS: PTSF:
ET= 1.2 ET= 1.1
ER= 1.0 fG=1.0 ER= 1.0 fG=1.0`
when it is level terrain, 600<vp<1200

A two-lane highway is currently operating at its two-way capacity in
rolling terrain. The traffic stream consists of cars and trucks only. A recent traffic
count revealed 720 vehicles (total, both directions) arriving in the most congested 15-
min interval. What is the percentage of trucks in the traffic stream based on the ATS
service measure?
Given:
ATS:
fG=0.99 when it is rolling terrain, vp>1200
ET= 1.5
when it is rolling terrain, vp>1200

A rectangular beam carrying a uniform load of 26 KN/m including its own weight is limited in cross section to 300 mm x 500 mm. The beam is simply supported in a span of 6 m. Using fc = 7 Mpa, fs = 124 Mpa, n = 12, ?? = 40 ???, ?? = 1.7 ???, ?????? ?ℎ? ????. Allow 65 mm distance from centroid of steel bars to extreme fibers.

During the construction of a building, what are the main environmental considerations which you should address?

use the tables of compound interest to look up the value of the factors. Do not use the interest formulas.

Two mutually exclusive alternatives are being considered. Both have lives of 5 years. Alternative 1 has a first cost of $2,500 and annual benefits of $746. Alternative 2 costs $6,000 and has annual benefits of $1,664. The minimum attractive rate of return (MARR) is 8%.

1. Use present worth analysis to determine which alternative should be selected.
2. Use annual cash flow analysis to determine alternative should be selected.
3. Use rate of return analysis to determine alternative should be selected.

Give at least 10 transportation and structural engineering topics for Capstone proposal or Thesis.

Q9. Explain your agreement or disagreement with the following statement: “Cyclical decoration should be restricted to rich areas only”. The answer should include a brief description of:

1. Cyclical decoration.

2. The relevance of cyclical decoration various tenants.

4. The procedure to be carried out.

Distinguish between hot mix asphalt patching and crack seal used for the maintenance treatment for flexible pavements.

A small catchment has an area of 680 ha and consist of Type-C soil. The land cover is 40% open space_good condition, 15% commercial and business area, 30% residential and 15% roads/paved area. Assuming normal moisture conditions, determine the volume of direct runoff from a design storm of total rainfall of 200 mm from this catchment. What would be value of runoff volumes if the past 5 day total rainfall were 10 mm and 70 mm, respectively, assuming growing season in catchment?

You are the city manager of a medium sized city in a rural area, around a population of 20,000. Your city applied for and received a grant from an organization that will allow you to develop a system of systems approach to the regional solid waste issues. What would be your approach? Look at how you could improve recycling, gain energy from the collected resources, reduce the amount of material sequestered into a landfill, and what would you do with items such as tires and e-waste. Your goal is to be creative yet efficient and maybe even break even on costs.

So, this week we are looking at how to govern the fragmented metropolis. The metropolitan battleground is fragmented along the space, race and ethnicity lines in both the cities and suburbs. How relevant is the State's input in metropolitan governance? Along the same line, walling off the suburbs by creating gated communities leads to spatial inequity in development. What are some ways central cities can gain some back some of this urban economic power?
